Zorluk: OrtaDeployment Strategies

A developer is configuring an AWS CodeDeploy deployment group for an in-place deployment to a fleet of 10 Amazon EC2 instances. The deployment must not provision any new EC2 instances due to budget limitations. Additionally, the application must maintain at least 50% of its healthy instance capacity at all times during the update to handle the incoming traffic load.

Which two CodeDeploy default deployment configurations can the developer select to meet these requirements? (Choose two.)

  1. CodeDeployDefault.OneAtATimeCevap
  2. CodeDeployDefault.HalfAtATimeCevap
  3. C
    CodeDeployDefault.AllAtOnce
  4. D
    CodeDeployDefault.ECSAllAtOnce
  5. E

Cevap

CodeDeployDefault.OneAtATime and CodeDeployDefault.HalfAtATime
The correct configurations are CodeDeployDefault.OneAtATime and CodeDeployDefault.HalfAtATime. An in-place deployment to a fleet of 10 EC2 instances requires at least 5 instances (50%) to remain healthy at all times. CodeDeployDefault.OneAtATime updates one instance at a time, keeping 90% capacity active. CodeDeployDefault.HalfAtATime updates up to 5 instances at a time, keeping exactly 50% capacity active. Both satisfy the minimum capacity requirement.

Adım Adım Çözüm

1
Analyze the deployment target and capacity constraints.
The deployment is in-place on a fleet of 10 EC2 instances and requires at least 50% capacity (5 instances) to remain healthy at all times.
To identify which deployment configurations are compatible with EC2 and satisfy the minimum instance count requirements.
2
Evaluate compatible CodeDeploy deployment configurations for EC2.
CodeDeployDefault.OneAtATime, CodeDeployDefault.HalfAtATime, and CodeDeployDefault.AllAtOnce are default configurations for EC2. Configurations prefixed with ECS or Lambda are incompatible.
To filter out platform-incompatible configurations.
3
Calculate the active capacity during deployment for the remaining configurations.
OneAtATime keeps 90% (9 instances) active. HalfAtATime keeps 50% (5 instances) active. AllAtOnce keeps 0% (0 instances) active. Only OneAtATime and HalfAtATime meet the 50% threshold.
To select the configurations that satisfy the capacity constraint.
